CPU Usage over 200%, normal?

  1. http://prntscr.com/ewyu3z

    Specs: (OVH Singapore)
    Intel Xeon E3-1245v5 | 4 Cores / 8 Threads | 3.5 GHz / 3.9 GHz | 32 GB DDR4 ECC 2133 MHz | 2x480GB SSD SOFT | Bandwith 3 TB /month

    That is survival server.
    sv = Survival
    sb = Skyblock
    cr = Creative
    sw = Skywars

    The only thing that i know is when the cpu usage gets 200% and higher, sometimes my players complain about stuck, which is TPS drop. Below that (something like <150%) is fine, TPS 19.5+

    Is it memory leak? Before i set it up with 6GB ram for Survival, then i set it to 8GB and the CPU usage decrease a bit.
  2. Depends on what wrappers (server versions) and plugin you have. The more reflective operations (wrappers do this most but the ones from plugins are more CPU intensive) happen, the more memory is taken. CPU usage comes in asynchronous tasks. Try to find memory leaks by one-by-one loading plugins onto a test server and stress testing it (spamming listeners and/or commands).
